Show Hint
The accessory carpal bone of the horse acts as a lever for the flexor carpi ulnaris and ulnaris lateralis muscles.
It articulates with only two structures: the radius (disto-posterior) and the ulnar carpal bone (posterior).
It articulates with only two structures: the radius (disto-posterior) and the ulnar carpal bone (posterior).

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
The carpus of the horse consists of several small bones arranged in two rows, plus the accessory carpal bone situated on the palmar (posterior) aspect.
Understanding the specific articular contacts of these carpal bones is crucial for diagnosing joint pathologies and lameness in horses.
Step 2: Detailed Explanation:
The accessory carpal bone (os carpi accessorium) is a disk-shaped bone positioned on the lateral and palmar aspect of the proximal row of carpal bones.
Due to its posterior projection, it serves as an insertion point for major flexor muscles, acting as a lever arm.
It has two distinct articular facets on its anterior (medial) face:
1. The dorsal facet articulates with the posterior (palmar) face of the distal extremity of the radius (Statement A).
2. The ventral facet articulates with the posterior (palmar) face of the ulnar carpal bone (Statement C).
It does not articulate with the anterior face of the radius (which is non-articular in this region) nor does it have any articular contact with the intermediate carpal bone.
Therefore, statements (A) and (C) correctly describe the articulations of the accessory carpal bone of the horse.
Step 3: Final Answer:
The correct option is (B), representing (A) and (C) only.
